Let's divide 358778 by 12
We're looking to find how many times 12 goes into 358778.

Advancing to step 1:
3 divided by 12 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 12

Advancing to step 2:
12 can be fit into 35 2 times, resulting in a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 24 from 35 leaves us with 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 12

Step 3:
118 divided by 12 is 9 with a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
If we subtract 108 from 118, we get 10.
Include the next digit (7) from the dividend after 10, then repeat: 107 / 12

Step 4:
12 can be fit into 107 8 times, resulting in a remainder of 11.
The next digit of our result is 8. 
Result so far: 298.0
If we take 96 away from 107, we end up with 11.
Bring next digit (7) of the dividend behind the 11 and repeat the process: 117 / 12

Going ahead to step 5:
If we divide 117 by 12, we get 9 and a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 2989.0
If we take 108 away from 117, we end up with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 12

Let's proceed to step 6:
12 goes into 98 8 times with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 29898.0
If we subtract 96 from 98, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
When dividing 20 by 12, we get 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 29898.1
Subtract 12 from 20 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 8:
The number 12 fits into 80 6 times, leaving a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 29898.16
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
If we divide 80 by 12, we get 6 and a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 29898.166
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 29898.166, and the remainder is 0.0008.
